Danube, Lariboisière received command of the artillery park. At the First Battle of Zurich, Lariboisière's artillery defended the Zurich heights, which gave Andre Massena's army enough time to evacuate the city and take position on the opposite side of the Limmat river. Afterward, Lariboisière was sent to northern Italy where he commanded the advance guard division; Jean Victor Moreau's right wing, with Lariboisière's infantry and artillery, crossed the Ticino river at Pavia, marched up the left bank of the Po River and took position beneath Alessandria; there, he protected Moreau's flank from Russian skirmishers sufficiently for Moreau to establish a large train of artillery in Turin and to strengthen the French positions between the Po and the Tanaro river. At Battle of Novi, his division was part of Laurent Saint-Cyr's right wing. At the battle itself, his troops were the only ones properly positioned; the rest of the French army was otherwise out of place and unready for battle. He and Saint-Cyr held the center of the French line, beating off two Russian assaults. After the French defeat at Novi, he went with Saint-Cyr to Savona, where he participated in operations around Genoa. Eventually, he rejoined Moreau to campaign in southwestern Germany, culminating in the Battle of Hohenlinden. Napoleonic Wars Baston de Lariboisière commanded the artillery of the French IV Corps for the 1805 campaign of the War of the Third Coalition. He directed the investment of Ulm prior to its capitulation, and contributed to the success of Austerlitz. There he commanded the artillery attached to Soult corps. By firing on the ice of the lakes over which the Russian columns were retreating, Baston de Lariboisière's artillery fire converted a Russian retreat into a full-scale rout: in the bombardment, French artillery pounded the soldiers and broke the ice. The men drowned in the cold ponds, dozens of Russian artillery pieces going down along with them. In the Battle of Jena-Auerstadt, Baston de Lariboisière successfully repelled several infantry charges with artillery fire. Subsequently, Napoleon raised him to major general, and appointed him to command the artillery of the Imperial Guard at Battle of Eylau, in February 1807. Baston de Lariboisière remained throughout the day-long battle with a battery of 40 guns at the French center. After the campaigns of 1806, Baston de Lariboisière briefly served as governor of Hanover. He later replaced General Nicolas-Marie Songis des Courbons prior to the engagements
